Stored procedures
Declares the default background color for the rectangles, circles, ... used in a picLayer variable.
Example
MyWDPic is WDPic = "Test.gif"
MyLayer is picLayer
 
// Declare the background color of different drawings
// made in MyLayer
MyLayer.Background(LightGreen)
 
IMG_MyDrawing = MyWDPic
Syntax
<picLayer image>.Background(<Color> [, <Fill style> [, <Type of hatching> [, <Opacity>]]])
<picLayer image>: picLayer variable
Name of the picLayer variable to use.
<Color>: Integer or constant
Default background color of different drawings. This color can correspond to:
  • an RGB color (returned by RGB),
  • an HSL color (returned by HSL),
  • a preset color of WLanguage.
  • a Color variable. In this case, the opacity specified in the variable is taken into account.
<Fill style>: Optional integer or Integer constant
Default background fill of different drawings:
BackgroundHatchedBackground filled with hatching.
Corresponds to value 2 for compatibility.
BackgroundSolid
(Default value)
Solid background.
Corresponds to value 0 for compatibility.
BackgroundTransparentTransparent background (<Color> is ignored).
Corresponds to value 1 for compatibility.

<Type of hatching>: Optional integer
Type of background hatching used by default in the different drawings. To use this parameter, the value of <Fill style> must be equal to 2. If the value of <Fill style> is different from 2, <Type of hatching> is ignored. The different types of hatching are:
  • 0: Horizontal hatching
  • 1: Vertical hatching
  • 2: Diagonal hatching at 60%
  • 3: Diagonal hatching at 120%
  • 4 (by default): Criss-crossed hatching
  • 5: Diagonal crossed hatching
<Opacity>: Optional integer
Opacity of color, included between 0 (transparent) and 255 (opaque). An opacity set to 128 is used to blend 50% of the color with the existing color found in the control.
Remarks:
  • This opacity will be taken into account if the drawing was initialized with the dWithOpacity constant (<picLayer variable>.StartDrawing).
  • Versions 23 and later
    If the <Color> parameter corresponds to a Color variable, this parameter must not be specified: the opacity specified in the variable will be taken into account.
    New in version 23
    If the <Color> parameter corresponds to a Color variable, this parameter must not be specified: the opacity specified in the variable will be taken into account.
    If the <Color> parameter corresponds to a Color variable, this parameter must not be specified: the opacity specified in the variable will be taken into account.
